JAR

1、Product Introduction

Jar is a kind of releasing tool when the drilling stem stuck happened.When drilling stuck happens, it may provide a big lifting or lowering force to release the stuck working pieces. The releasing force will be produced through lifting/lowering operation on the ground.It have the advantages of easy operation, reliable and widely used in drilling,coring ,fishing and repairing of the down hole operation.

2、Place of manufacture: Shanghai

3、Lead time:1-3 months
